Polyoxometalates (POMs) are complex inorganic ions self-assembled from multiple metals and oxygen. Electrochemical analysis of single atom bridged monosubstituted ions in solution have demonstrated unusual redox properties. The investigation was to discern whether concentration would affect the redox potential, which was tested using cyclic voltammetry. The samples tested were prepared using the POM [P2W17O61]10- bridged by gadolinium(III). Previous testing has already demonstrated a shift in potential when the concentration of potassium ions has been varied. This investigation demonstrated what effect the actual concentration of the POM ions has on this phenomenon by studying the same K+:POM ratio with varying POM concentration.
